Indoor acoustics essay
1. Indoor acoustics
The enviroment in which the interview was recorded was a excluded corridor in the
henley college, rarely used this corridor was a well chosen location to place a
interview, due to the surroundings not being sound proofed and there being the
opportunity for interferences to take place the interview did not come out in
good quality, some was too quiet because both the interviewer and the
interviewee were to far away from the microphone. The Microphone not
having a stand or being able to sit at mouth height caused problems because
the distance that the sound waves had to travel to reach the microphone was
constantly changing often making the interview too quiet for listeners to hear,
had to be edited to alter these problems.
If the interview was better planned it would of taken place in a acoustically treated
room, or if the funds aren’t quite there using egg boxes as the soundproofing
and removing all interference or chances of interference from the room e.g.
mobile phones. For this type of interview using a dead room would have been
ideal, which is a room, which does not echo or allow reverberation, where as a
live room allows sound waves to travel and bounce around the room, allowing
echo and reverberation, like in a church, so that the sound of a voice can travel
across a room. The ideal microphone for this situation would be a condenser
microphone because of its capability to re produce a clear sound.
Outdoor Acoustics
The recording was done on the main road outside the Deanfield Library at the Henley
college, usually this road is constantly busy, heaving with students commuting
to lessons or people driving up and down the road so can be a very noisy
enviroment. The recording was done during a lesson which is the only time
that road is less populated, cars lorrys and buses still travel down the road
making the location difficult to record in as the microphone picks up the sound
of the engine 10 seconds or so before it even passes it.
When recording outside a lot more care has to be taken into viewing your
surroundings and noise risks, which may interfere with the quality of your
recording. Because sound proofing is not possible when outside your location
has to be wisely picked, not too close to a road because of the car noises, no
where near radio towers mobile telephones because interference will be picked
up on the microphone, these are called ambient sounds. If recording an
interview outside, a condenser microphone would be the ideal microphone to
choose because it can deal with higher pressure level, that’s why it is used in
recording instruments because when recording a band, the amps will have
other music playing out of it so the microphone needs to be able to pick up the
sound coming from the instrument clearly without the other sounds causing a
interference. Microphones are very sensitive, when recording a wind is very
easily picked up on the microphone, ruining the recording.

Simulated effects
2. Working in a recording industry is a difficult task, when recording problems are faced
on a regular basis, the recording may not play back as well as hoped or the
sound effect needs to be adjusted so there has to be some effects which you
can use to alter the voice or sound being recorded to perfect it, often used in
the music industry is the effect auto tune, by known rappers/singers such as
Kanye West, T-Pain, Lil Wayne & many other artists. The problem with auto
tune is that when used to its full effect it is obvious that the original voice has
been edited. (Insert auto tune effect) A lot of artist’s use it and it’s not obvious
that the voice has been altered with the high pitched sound hears through T-
Pain. Many artists have admitted to using Auto tune, an embarrassing effect to
admit you have used, disclaiming there own musical talent and having to
recreate it. Mary J Blige has also used Auto tune, in her song “The One”
(insert example of track) Auto-Tune was designed by Antares Audio
Technologies released in 1997, The way the program works is that it takes a
sound and adjusts the tone by blending the “pitch to the nearest true semitone”
http://en.wikipedia.org/wiki/Auto-Tune which makes artists who sing a note
slightly offkey able to produce pitch perfect sounds. A talk box is another
simulated effect commonly used by artists and recording studio to adjust the
pitch of a note, this is done manually whilst recording instead of in added to
the soundtrack in post-production. Here is how the talk box sounds; (insert
talk box sound effect) the talk box is used by connecting the pedal to the
instrument (e.g guitar) and to alter the sound the tube is put into the mouth of
the user and by moving your mouth the notes change according to your mouth
movements.
